Sharon Armstrong was a former deputy chief executive of the Maori Language Commission and was heading to London to meet her internet boyfriend who had asked her to travel via Argentina and pick up a weighty paper contract for him.

But when she got to customs she got a shock.

“They lifted the bottom of the bag up and I immediately saw there were three packages that were wrapped in masking tape,” says Armstrong.

Customs officials found more than five kilograms of cocaine in her luggage.

Her family have said she was conned, and had no idea she was carrying drugs - she trusted her boyfriend.
